Description

  The present invention relates to a combine that harvests and thresh cereal grains and stores the threshed grains.

  Generally, a combine that threshs while harvesting crops in a field and stores the grains in a glen tank is known. The grains stored in the Glen tank are discharged out of the machine from the discharge auger, and are shipped to the market through an inspection to confirm the quality. In this inspection, cracks and cracks in the grain, foreign matter contamination, etc. are detected, and the quality of the harvest is assessed.

  Conventionally, a combine unit has been proposed in which a measurement unit is provided in a grain tank that stores grains, and the quality of the grains supplied to the internal space of the grain tank is measured by the measurement unit (see Patent Document 1). The measurement unit has a box-shaped measurement chamber forming body with a built-in quality sensor that measures the quality of the grain, and a cylindrical holding portion forming body that passes the grain that performs quality measurement by the quality sensor. ing. The holding part forming body supports a shutter that forms a temporary storage part for temporarily storing the grains by closing the discharge port, and an upper part of the temporary storage part has an amount necessary for measurement by the quality sensor. A proximity sensor for detecting whether or not the grain is stored in the temporary storage unit is provided.

It is characterized by that.

  In addition, although the code | symbol in the said parenthesis is for contrast with drawing, it does not limit the structure of this invention at all.

  According to the first aspect of the present invention, since control is performed so that the quality measuring unit is not operated at the start or end of cutting, the reliability of the obtained data can be improved.

  According to the second aspect of the present invention, since the determination of the start of cutting and the end of cutting is executed based on at least one of the machine body information and the harvest information, the start of cutting and the end of cutting can be reliably determined.

  According to the third aspect of the present invention, the shutter is held in the open position at the start of cutting or at the end of cutting, so that it is possible to prevent contamination from entering the temporary storage unit, and the reliability of data measured by the quality measuring unit. Can be improved.

  Since the present invention according to claim 4 switches the operation and non-operation of the quality measurement unit based on the measurement result of the layer thickness sensor, for example, when the layer thickness is thin in a situation where there are many impurities, the quality measurement unit is not activated. As an operation, the reliability of the obtained data can be improved.

  Next, the measurement unit 61 will be described in detail with reference to FIGS. As shown in FIGS. 7 to 9, the measurement unit 61 includes an attachment plate 62 attached to the top plate 9 a of the Glen tank 9, and a temporary storage tank 63 fixed to the attachment plate 62 and arranged inside the Glen tank 9. And a handle 65 and a camera 66 (imaging unit) fixed to the mounting plate 62, and a quality measurement sensor 67 (quality measurement unit) fixed to the temporary storage tank 63. As shown in FIG. 9, the temporary storage tank 63 is formed with a supply port 63 a through which the grain is supplied and a discharge port 63 b through which the grain supplied from the supply port 63 a is discharged into the Glen tank 9. A shutter 69 is rotatably supported by the temporary storage tank 63 about the rotation shaft 69a between the supply port 63a and the discharge port 63b. The shutter 69 is movable by a shutter opening / closing motor 70 (see FIG. 8) between an open position for opening the discharge port 63b and a closed position for shielding the discharge port 63b.

  A back wall 72 is provided on the back side of the front wall 71 where the supply port 63 a is formed, and a quality measurement sensor 67 is housed inside the back wall 72. A hole 62 a is formed in the mounting plate 62 so as to correspond to the position of the lens of the camera 66. A storage space SP for temporarily storing grains is formed by the mounting plate 62, the front wall 71, the back wall 72, the side wall 73 (see FIG. 8), and the shutter 69. As shown in FIG. 8, a measurement grain sensor 74 (storage detection unit) is provided inside the side wall 73, and the measurement grain sensor 74 is pressed by the grain stored in the storage space SP. Thus, the measurement grain sensor 74 is turned on. That is, the measurement grain sensor 74 outputs a detection signal based on the fact that the grain is stored in the temporary storage tank 63. When attaching or detaching the measurement unit 61, the handle 65 is gripped.

  FIG. 10 shows a modification of the present embodiment, in which a camera 166 is attached to the side plate 9b instead of the top plate 9a of the Glen tank 9. In other words, the grain stored in the temporary storage tank 63 can be imaged from the side rather than from above. In this case, the wall surface 166A of the temporary storage tank 63 facing the camera 166 is made of a transparent member, and the camera 166 images the grains in the storage space SP via the transparent wall surface 166A of the temporary storage tank 63. .

  FIG. 11 shows a control block diagram according to the present embodiment, and the combine 1 includes a control unit 100 that includes a microcomputer (including a CPU, a ROM, a RAM, and the like) and constitutes the control block diagram. On the input side of the control unit 100, a camera 66, a quality measurement sensor 67, a measurement grain sensor 74, tank storage amount detection sensors 75 a to 75 e, a shutter open / close detection sensor 76, a display changeover switch 31, a traveling main transmission lever 22, a multi A steering lever 29, a cutting height detection sensor 77, a power clutch switch 26, a machine body position detection sensor 79, a transported culm detection sensor 80, a layer thickness sensor 81, and the like are connected.

  The shutter opening / closing detection sensor 76 detects the opening / closing position of the shutter 69 of the temporary storage tank 63, and the cutting height detection sensor 77 detects the elevation height of the cutting unit 6. Airframe position detection sensor 79 is composed of, for example, a GPS sensor, and can detect the current position of the body of combine 1. The transporting culm detection sensor 80 is provided in the cutting unit 6 and can detect the presence or absence of transporting of the culm.

  Image data analysis result data 101 is generated from the image captured by the camera 66, and analysis result data 102 is generated from the detection result of the quality measurement sensor 67. The quality measurement sensor 67 uses, for example, an optical detection method. That is, the moisture / protein content can be measured by irradiating the grain with light and measuring the intensity for each wavelength in the near infrared region of the light transmitted through the grain or the reflected light. Generally, when the protein content of the grain is high, it is hard and less sticky, the taste is poor, and the protein content is preferably 5 to 8%. Moreover, drying time can also be adjusted by grasping | ascertaining the moisture content of a grain.

  Airframe information data 109 relating to the airframe 3 is generated from the operation positions or detection results of the traveling main transmission lever 22, the multi-steer lever 29, the cutting height detection sensor 77, the power clutch switch 26, and the airframe position detection sensor 79. Harvest information data 111 relating to the harvest is generated from the transported culm detection sensor 80 and the layer thickness sensor 81. The image data analysis result data 101, the analysis result data 102, the machine body information data 109, and the harvest information data 111 are stored in the data storage unit 105. The image data analysis result data 101 and the analysis result data 102 obtained at the same timing can be stored in the data storage unit 105 (storage unit) in a state in which these data are associated by the related data generation unit 103. .

  A shutter opening / closing motor 70 (drive unit), the display monitor device 30, an external server 82, a threshing ability adjusting mechanism 83, and a sorting ability adjusting mechanism 85 are connected to the output side of the control unit 100. The control unit 100 is connected to the external server 82 via the communication unit 106, and the control unit 100 and the external server 82 are configured to be able to communicate with each other. The threshing ability adjusting mechanism 83 is a mechanism that adjusts the threshing ability of the threshing unit 35, and can change the opening degree of the dust feed guide 42 provided in the handling chamber 40 and the rotational speed of the handling cylinder 41, for example. The sorting ability adjusting mechanism 85 is a mechanism for adjusting the sorting ability of the sorting unit 36, and can change, for example, the fin opening of the chaff sheave 52 and the rotation speed of the tang fan 46 and the blower fan 47. In addition, the control unit 100 includes a cutting determination unit 107 that determines the start or end of cutting during the cutting operation using at least one of the machine information data 109 and the harvest information data 111.

  Next, the control of the measurement unit 61 will be described with reference to the flowchart shown in FIG. As shown in FIG. 12, when the control of the measurement unit 61 is started, the control unit 100 first determines whether the stop flag is “1” or “0” (step S1). When the stop flag is “0” (step S1: “0”), the control unit 100 determines whether or not the cutting operation is being performed (step S2). Whether or not the cutting operation is in progress is determined by the cutting determination unit 107 of the control unit 100 based on at least one of the body information data 109 and the harvest information data 111. For example, the power clutch switch 26 is ON, the height of the cutting unit 6 is located at a cutting operation position where the height is less than a predetermined height, the transporting culm detection sensor 80 is ON, and the layer thickness sensor 81 is equal to or greater than a predetermined amount. If at least one of the certain machine body position is located at the midway position of the straight line instead of the end of the field, the cutting determination unit 107 determines that the cutting operation is being performed. Note that it may be determined that the cutting operation is being performed by satisfying any one of these conditions, and a combination of these conditions may be freely set.

  When it is determined that the cutting operation is being performed (step S2: YES), the control unit 100 executes a determination process as to whether the cutting starts or ends (step S3). The cutting determination unit 107 of the control unit 100 determines whether cutting starts or ends based on at least one of the machine body information data 109 and the harvest information data 111. For example, when the power clutch switch 26 is ON and the height of the cutting unit 6 is within a predetermined time after returning to the cutting operation position from the rising position where the height is greater than or equal to a predetermined height, the conveying pallet detection sensor 80 is changed from OFF to ON. Within a predetermined time after switching, immediately after the turning operation by the multi-steer lever 29 is completed, the layer thickness sensor 81 is less than a predetermined value, the machine body position is the end of the field, and the end position of the linear strip If at least any one of the neighboring positions is satisfied, the cutting determination unit 107 determines that cutting has started.

  For example, the power clutch switch 26 is ON, the height of the cutting part 6 is switched from the cutting work position to the raised position within a predetermined time, and the transported culm detection sensor 80 is switched from ON to OFF within the predetermined time. Immediately after the turning operation by the multi-steer lever 29 is started, the layer thickness sensor 81 is less than a predetermined value, and the body position is located at the end of the field and in the vicinity of the end position of the linear strip. If at least one of them is satisfied, the cutting determination unit 107 determines that the cutting has been completed. In addition, it may determine with it being the cutting start or the cutting end by satisfy | filling any one of these conditions, and you may set the combination of these conditions freely.

  Of course, the start or end of cutting may be determined based only on the measurement result of the layer thickness sensor 81. That is, when the layer thickness of the processed material on the rocking sorter 45 is thin and the layer thickness sensor 81 measures a layer thickness less than a predetermined value, it may be determined that cutting starts or ends. Then, as will be described later, when it is determined that cutting starts or ends, the property measurement (step S7) by the quality measurement sensor 67 is not performed, and therefore the control unit 100 determines the measurement result of the layer thickness sensor 81. Based on this, the quality measurement sensor 67 is switched between operation and non-operation.

  When it is determined that it is not the start or end of cutting (step S3: NO), the control unit 100 determines whether the shutter 69 of the temporary storage tank 63 is in the closed position based on the detection result of the shutter opening / closing detection sensor 76. Is discriminated (step S4). When the shutter 69 is not located at the closed position (step S4: NO), the control unit 100 drives the shutter opening / closing motor 70 so that the shutter 69 is located at the closed position (step S5), and returns to step S4.

  When the shutter 69 is in the closed position in step S4 (step S4: YES), the control unit 100 determines whether or not the measured grain sensor 74 is ON for a predetermined time (step S6). That is, when the measurement grain sensor 74 is turned on for a predetermined time, the storage amount of the grain suitable for the following property measurement and imaging can be recognized. In addition, you may comprise so that the storage amount of the grain in the temporary storage tank 63 may be detected by measuring the elapsed time from the start of a cutting operation, without using the measurement grain sensor 74. FIG.

  When the measurement grain sensor 74 is ON for a predetermined time (step S6: YES), the control unit 100 activates the quality measurement sensor 67 and the camera 66 to perform grain property measurement and imaging (step S7, S8). These property measurement and imaging may be performed once or a plurality of times, and an average of data obtained by a plurality of property measurement and imaging may be taken. The analysis result data 102 and the image data analysis result data 101 obtained by the property measurement and imaging are stored in the data storage unit 105 in a state in which these data are associated by the related data generation unit 103. The data stored in the data storage unit 105 may be output to the external server 82 via the communication unit 106, or may be output directly to a smartphone or an external computer, such as a USB or CD-ROM. You may make it possible to take out outside via a storage medium.

  When the property measurement and imaging operations (steps S7 and S8) are completed, the control unit 100 determines whether or not the shutter 69 of the temporary storage tank 63 is located at the open position (step S9). When the shutter 69 is not in the open position (step S9: NO), the control unit 100 drives the shutter opening / closing motor 70 so that the shutter 69 is in the open position (step 10), and returns to step S9.

  When the shutter 69 is in the open position (step S9: YES), the control unit 100 determines that the grain storage amount of the grain tank 9 is a predetermined value based on the detection results of the tank storage amount detection sensors 75a to 75e. It is determined whether or not this is the case (step S11). For example, in the present embodiment, as shown in FIG. 6A, when the tank storage amount detection sensors 75a to 75c are turned ON, the storage amount of the grain in the Glen tank 9 is equal to or greater than a predetermined position. judge. Thus, when the grain in the Glen tank 9 is stored more than the height of the tank storage amount detection sensor 75c, the grain stored in the Glen tank 9 and the shutter 69 may interfere with each other. If the shutter 69 interferes with the grain, the shutter opening / closing motor 70 may be overloaded or the shutter 69 may be damaged when the shutter 69 is opened / closed.

  As shown in FIG. 12, when it is determined in step S11 that the tank storage amount of the Glen tank 9 is less than the predetermined value (step S11: NO), the control unit 100 sets the stop flag to “0”. Control ends (step S12). When it is determined in step S11 that the tank storage amount of the Glen tank 9 is equal to or greater than the predetermined value (step S11: YES), the control unit 100 sets the stop flag to “1” and ends the control (step S13). ).

  Further, when the stop flag is “1” in step S1 (step S1: “1”), when it is determined in step S2 that cutting is not in progress (step S2: NO), and in step S3, the start of cutting or cutting When it determines with it being the end (step S3: YES), the control part 100 discriminate | determines whether the shutter 69 of the temporary storage tank 63 is located in an open position (step S14). When the shutter 69 is not in the open position (step S14: NO), the control unit 100 drives the shutter opening / closing motor 70 so that the shutter 69 is held in the open position (step 15), and the process returns to step S14. .

  When the shutter 69 is located at the open position (step S14: YES), the controller 100 determines that the grain storage amount in the Glen tank 9 is a predetermined value based on the detection results of the tank storage amount detection sensors 75a to 75e. It is determined whether it is less than (step S16). When it is determined that the tank storage amount of the Glen tank 9 is less than the predetermined value (step S16: YES), the control unit 100 sets the stop flag to “0” and ends the control (step S17). When it is determined in step S16 that the tank storage amount of the Glen tank 9 is equal to or greater than the predetermined value (step S16: NO), the control unit 100 ends the control while keeping the stop flag “1”. The above control is repeated while the threshing clutch of the combine 1 is ON. That is, during the harvesting operation, the storage of the grain in the temporary storage tank 63, the measurement and imaging of the grain properties, and the discharge of the grain into the Glen tank 9 are repeated.

  Since the present embodiment is configured as described above, it is possible to perform image capturing of the grain by the camera 66 and measurement of the quality of the grain by the quality measuring sensor 67 during the cutting operation that is not the start or end of cutting. . At this time, the grain whose image and property are measured is a grain in a stopped state stored in the temporary storage tank 63 in the Glen tank 9. For this reason, a grain can be stably imaged and property-measured, and highly reliable image data and property analysis data can be obtained.

  From the image data analysis result data 101 obtained from the image captured by the camera 66, based on the color, size, shape, etc., the rough grain taste and the amount of contaminants such as waste and weeds are recognized. Can do. In addition, it is possible to recognize the presence and amount of grains damaged at the time of threshing, grains contaminated with mud or oil, grains with remaining branches, normal grains with high quality, and the like. Further, from the analysis result data 102 obtained by the quality measurement sensor 67, it is possible to measure the moisture and protein content of the grain.

  Then, the control unit 100 adjusts the threshing ability adjustment mechanism 83 and the sorting ability adjustment mechanism 85 according to the image data analysis result data 101. In addition to the threshing ability adjusting mechanism 83 and the sorting ability adjusting mechanism 85, the vehicle speed may be automatically adjusted. For example, when there are many impurities, the opening degree of the dust feeding guide 42 is set large. For example, when there are many damaged grains, the opening degree of the dust feed guide 42 is set large and the fin opening degree of the chaff sheave 52 is increased. For example, when there are a lot of grains with branch branches remaining, the opening degree of the dust feed guide 42 is set small, and the fin opening degree of the chaff sheave 52 is reduced. In addition, when there are many dirty grains, a warning is displayed on the display monitor device 30 or other notification means (lamp, horn, etc.) is notified. Further, when the grain is large, the sorting wind can be strengthened to improve the sorting accuracy, and when the grain is small, the sorting wind can be weakened to suppress scattering outside the machine.

  Note that the image captured by the camera 66 may be displayed on the display monitor device 30 in the driving operation unit 8, and the operator may be able to confirm the storage stored in the temporary storage tank 63 in real time. . Thereby, the operator judges from the image of the display monitor device 30 and, for example, when there are many foreign objects, the operator operates the selection dial in the operation operation unit 8 to adjust the air volume of the tang fan 46 and the blower fan 47. You may make it adjust and the fin opening degree of the chaff sheave 52 manually. Further, the vehicle speed may be adjusted.

  Further, the image data analysis result data 101 and the analysis result data 102 obtained at the same timing are associated with each other by the related data generation unit 103 and stored in the data storage unit 105. If it is determined that there are many, the analysis result data 102 associated with the image data analysis result data 101 may not be adopted as having low reliability. Thereby, the analysis result data 102 with higher reliability can be obtained. In addition, when it is determined by imaging of the camera 66 that there are many impurities in the storage in the temporary storage tank 63, the shutter 69 is controlled to be in the open position without performing the property measurement by the quality measurement sensor 67. However, it may be configured to forcibly discharge a large amount of contaminants. Further, GPS information or other machine information may be further associated with the related data of the image data analysis result data 101 and the analysis result data 102.

  In addition, a shutter 69 capable of opening and closing the discharge port 63b of the temporary storage tank 63 is provided, and since the measurement grain sensor 74 detects that the grain is stored in the storage space SP of the temporary storage tank 63, the temporary storage tank It is possible to prevent the camera 66 and the quality measurement sensor 67 from performing imaging and property measurement when there is no storage in 63.

  Further, in the present embodiment, the shutter 69 of the temporary storage tank 63 is controlled to be opened at the start or end of cutting, and the temporary storage tank 63 is in a state where the shutter 69 is in the open position. Grains are not stored in the storage space SP, and imaging and property measurement by the camera 66 and the quality measurement sensor 67 are not performed. This is because the layer thickness of the processed material on the rocking sorter 45 is often thin at the beginning or end of cutting, and in this state, impurities in the processed material easily fall together with the grains. . And at the beginning or end of cutting, the amount of impurities mixed in the grains stored in the temporary storage tank 63 increases, and the reliability of the obtained data is not high.

  Therefore, the combine 1 according to the present embodiment does not operate the quality measurement sensor 67 at the start or end of cutting, and operates the quality measurement sensor 67 in a state where the flow of the processed material is stable. Can be obtained. In addition, since the shutter 69 remains in the open position at the beginning or end of cutting, contamination of the temporary storage tank 63 can be reduced.

  Next, a second embodiment of the present invention will be described. In the second embodiment, an inlet shutter is added to the supply port 63a of the temporary storage tank 163. For this reason, about the structure similar to 1st Embodiment, illustration is abbreviate | omitted or attaches | subjects the same code | symbol to a figure and demonstrates.

  As shown in FIG. 13, the measurement unit 161 includes a temporary storage tank 163 disposed inside the Glen tank 9 (see FIG. 6A), a camera 66 fixed to the temporary storage tank 163, and a quality measurement sensor 67. A shutter 69 that can close the discharge port 63b, and an entrance shutter 120 that can close the supply port 63a.

  The inlet shutter 120 is supported by the temporary storage tank 163 so as to be rotatable between an open position and a closed position around a rotation shaft 120a. When the inlet shutter 120 is located at the open position (position indicated by a solid line), the supply port 63a is opened, and the grain can be input into the storage space SP from the supply port 63a. When the inlet shutter 120 is located at the closed position (position indicated by a two-dot chain line), the supply port 63a is closed, and the grain cannot be input into the storage space SP from the supply port 63a.

  The entrance shutter 120 is opened and closed by a driving force of a motor (not shown) or a shutter opening / closing motor 70 (see FIG. 11). Then, the control unit 100 controls the motor so that the entrance shutter 120 is in the closed position when the camera 66 captures an image, and is in the open position when the imaging of the camera 66 is completed. Thereby, a grain is thrown in from the supply port 63a at the time of the imaging of the camera 66, and the image of the camera 66 is not disturbed, a clear image is obtained, and more reliable data can be obtained.

  Next, a third embodiment of the present invention will be described. In the third embodiment, the camera 66 is omitted from the measurement unit 61 of the first embodiment, and the measurement unit 261 is configured. For this reason, about another structure, about the structure similar to 1st Embodiment, illustration is abbreviate | omitted or attaches | subjects the same code | symbol to a figure and demonstrates.

  As shown in FIGS. 14A and 14B, the measurement unit 261 has a temporary storage tank 63 and a quality measurement sensor 67 fixed to the temporary storage tank 63. Regarding the control of the measurement unit 261, step S8 in the flowchart shown in FIG. 12 is omitted, and the rest is the same as in the first embodiment, and thus the description thereof is omitted. Thus, even if the camera 66 is omitted, the quality measurement sensor 67 does not operate at the beginning or end of cutting, so that highly reliable data can be obtained.

  The quality measurement sensor 67 may be of any type, and not only a near infrared spectroscopy type taste sensor but also a capacitance analysis type moisture sensor may be used.

  Moreover, although it demonstrated using the self-decomposing type combine in any form mentioned above, you may apply this invention to the general purpose combine which can harvest soybean, wheat, etc. besides rice.
